Amazon dropped the price of the SanDisk Class 10 Ultra 128GB MicroSD XC Card to $99.99 with free shipping. That’s $20 off the lowest price we’ve seen hand half off of retail for this super fast 30MB/s Micro SD card. Use it in your Android Phone to add 128GB of storage or with the free adapter (included) you can put it in a SD camera or a Mac (or any device that accepts SD Cards).
